Disconnect/Shorting Bar c/w Cover
Model A3504 Switch

This Switch Assembly is designed to provide a disconnecting means for your watt transducer.Not only can this Switch Assembly provide isolation from line voltages, it also will short out current transformer secondaries, adding considerable safety against high potential electrical shock from live open CTs.The botton side of the switch is connected to the circuits being measured. The top side of the switch is connected to the watt transducer. The switch handles are colour coded red for voltage and black for current. The black plastic cover is constructed so that all switches must be in the closed position before the cover can be sealed.


These Current Transformers provide a low amperage current output proportional to line current, for use in building automation, relaying, or metering. The core and windings of each unit are completely encased in UL approved plastic that is rated 94V1, and there are no exposed metal parts other than the terminals.

Solid Core Current Transformers

These solid core Current Transformers are available
in two sizes and a wide range of current ratios.

Insulation class: 0.6 Kv 10 Kv BIL
Frequency: 50-400 Hz
Approximate weight: Model 5RL: .45 kg (1.0 lb)
Model 7RL: .68 kg (1.5 lb)

Split Core Current Transformers

These split core Current Transformers are designed to be assembled around an existing (insulated) conductor without the need for dismantling the primary bus or cables. The portion of the transformers marked "THIS END REMOVABLE" can be disassembled and then reassembled around the conductors that require current monitoring.
